This abstract introduces 4-core electrical wires cables, with specifications covering 10mm² and 25mm², rated voltage of 0.6/1kV, designed with pure copper conductors and PVC insulation.​ In terms of specifications, "4-core" means each cable contains 4 independent conductors, and 10mm² and 25mm² are the cross-sectional areas of a single conductor. The 10mm² cable has a long-term allowable current-carrying capacity of about 50-60A in a 30℃ environment, suitable for power transmission of 11-13kW under 220V voltage, such as small air compressors and partial power distribution in office buildings. The 25mm² cable has a current-carrying capacity of 90-100A, capable of carrying 19-22kW under 220V voltage, applicable to shopping mall air conditioning units and main cables of workshop production lines. The rated voltage of 0.6/1kV meets the requirements of low-voltage power distribution systems and can be connected to civil or industrial low-voltage power grids.​ In terms of materials, the pure copper conductor has a conductivity of 100% IACS, with low transmission loss, high mechanical strength and excellent bending resistance. The PVC insulation layer can withstand temperatures from -15℃ to 70℃, with an insulation resistance of ≥10¹⁴Ω·cm, which can effectively insulate current and has the characteristics of moisture resistance and chemical corrosion resistance. The overall structure is circular, with the sheath tightly wrapped, suitable for various laying methods such as pipe threading and direct burial.​ This cable is widely used in power supply of industrial equipment, power distribution in commercial places and lines in civil buildings, balancing safety and transmission efficiency.

This single core building wire is a core wiring product specially designed for indoor power transmission in buildings. Its core configuration includes a flexible pure copper stranded conductor, a 90°C high-temperature resistant PVC insulation layer, with a rated voltage of 600V, and covers three standard cross-sectional specifications: 2.0mm², 4.0mm², and 6.0mm². It combines flexibility, safety, and versatility, and is widely suitable for power supply of lighting, sockets, small and medium-sized electrical appliances, and power equipment in scenarios such as residences, commercial buildings, and small industrial workshops. It is a basic wiring choice that balances performance and practicality in building electrical systems.​ In terms of core performance and materials, the flexible pure copper stranded conductor is the key guarantee for its flexibility and conductivity. The conductor is made of electrolytic copper with a purity of ≥99.95%, twisted from multiple strands of fine copper wire - the 2.0mm² specification is usually composed of 19 strands of 0.37mm copper wire, the 4.0mm² is 19 strands of 0.52mm copper wire, and the 6.0mm² is 37 strands of 0.46mm copper wire. The multi-strand twisted structure greatly improves the flexibility of the wire, with a minimum bending radius of only 6 times the outer diameter of the wire. Even in narrow or complex wiring spaces such as narrow gaps in building walls, ceiling interlayers, and behind furniture, it can be easily bent and routed, avoiding the problem that single-strand solid conductors are easy to break and difficult to operate, and significantly reducing construction difficulty. At the same time, high-purity pure copper endows the conductor with excellent conductivity. The DC resistance of the 2.0mm² specification at room temperature is ≤8.21Ω/km, 4.0mm² is ≤4.11Ω/km, and 6.0mm² is ≤2.74Ω/km, which is much lower than the industry average. It can effectively reduce energy loss during current transmission, ensuring stable lighting brightness and efficient electrical operation. For example, when a 2.0mm² wire supplies power to a 10-meter-long LED light strip (power 20W), the voltage drop is only 0.03V, which is almost negligible.​ The 90°C high-temperature resistant PVC insulation layer provides reliable protection and environmental adaptability for the wire. The insulation layer is made of modified PVC material, added with high-temperature resistant stabilizers and flame retardants. It can not only maintain structural stability in a continuous high-temperature environment of 90°C, avoiding insulation softening, aging or short circuit, but also withstand short-term overload high temperatures of 130°C (such as heat generated at the moment of electrical startup). Compared with ordinary building wires with a temperature resistance of 60-75°C, its high-temperature resistance can be adapted to scenarios closer to heat sources, such as wiring around kitchen appliances and power supply lines for computer room equipment. At the same time, the PVC insulation layer has excellent electrical insulation, with an insulation resistance of ≥10¹⁴Ω·cm at room temperature and a dielectric strength of ≥20kV/mm, which can effectively isolate the conductor from the external environment and prevent electric leakage accidents. It also has certain acid and alkali resistance and moisture resistance. In humid areas such as bathrooms and basements or environments exposed to slight cleaning agent residues, it can still maintain insulation integrity and extend the service life of the wire.​ The 600V rated voltage and multi-specification coverage make it suitable for diverse building electricity needs. The 600V rated voltage complies with the low-voltage power distribution system standard, which can not only meet the needs of 220V single-phase lighting and socket circuits in residences and commercial buildings, but also adapt to the power supply of 380V three-phase power equipment (such as small air compressors and water pumps) in small industrial scenarios, with strong compatibility. The three cross-sectional specifications accurately match different load scenarios: the 2.0mm² specification has a rated current-carrying capacity of about 16-20A, mainly used for lighting circuits and power supply of small household appliances (such as desk lamps, routers, set-top boxes), and is the main specification for lighting wiring in residential bedrooms and living rooms; the 4.0mm² specification has a current-carrying capacity of about 25-32A, suitable for socket circuits in kitchens, bathrooms and other areas, and can carry medium-power appliances such as washing machines, refrigerators, and electric water heaters (2-3kW); the 6.0mm² specification has a current-carrying capacity of about 35-45A, targeting high-power equipment such as air conditioners (2.5-5kW) and small industrial motors (1-3HP), which can stably transmit current and avoid wire heating or equipment failure caused by overload.​ In terms of application scenarios, relying on its versatility and adaptability, this wire covers multiple core links of building electrical systems. In residential buildings, 2.0mm² is used for lighting wiring throughout the house, 4.0mm² is matched with socket circuits, and 6.0mm² is specially wired for high-power household appliances such as air conditioners and electric water heaters, forming a layered power supply system to ensure electricity safety; in commercial buildings (such as office buildings and shops), 2.0mm² is suitable for office lighting and sockets of office equipment such as computers and printers, 4.0mm² is used for power supply of conference room projectors and small air conditioners, and 6.0mm² can meet the needs of equipment such as store freezers and display cabinets; in small industrial workshops, the 6.0mm² specification can be connected to power devices such as small machine tools and ventilation equipment, and 2.0mm² and 4.0mm² are used for workshop lighting and control circuits, realizing separate wiring of power and lighting systems for easy management and maintenance.​ Overall, through the flexibility of the flexible pure copper stranded conductor, the high-temperature safety of the 90°C PVC insulation, and the wide adaptability of 600V voltage and multi-specifications, this single core building wire not only solves the wiring problems in complex building environments, but also meets the power supply needs of equipment with different powers. It provides stable, safe and long-term power transmission support for various building electrical systems and is an indispensable basic electrical component in building construction.

The 2.5/4/6mm² BVR flexible electrical cable, a core wiring product in the home and building sectors, has become the preferred solution for residential electricity use and commercial building circuit installation, thanks to the excellent performance of its pure copper conductor and flexible structural design. Its core advantage first lies in the conductor material: it uses high-purity oxygen-free copper with a purity of ≥99.99%. Compared with ordinary electrolytic copper, it not only has better electrical conductivity (the DC resistance of the conductor at 20℃ is ≤13.3Ω/km for 2.5mm², ≤8.21Ω/km for 4mm², and ≤5.38Ω/km for 6mm², far lower than the industry average standard) but also exhibits stronger oxidation resistance and corrosion resistance. This effectively prevents issues such as increased line loss and abnormal heating caused by conductor oxidation during long-term use, adapting to the long-term electricity demand of 10-20 years in homes and buildings.​ In terms of structural design, the BVR cable adopts a multi-strand fine copper wire stranding process (2.5mm² consists of 19 strands of Φ0.41mm copper wire, 4mm² of 37 strands of Φ0.37mm copper wire, and 6mm² of 49 strands of Φ0.41mm copper wire). Compared with single-strand rigid wires (BV wires), its flexibility is significantly improved, with a minimum bending radius of only 4 times the cable outer diameter (taking the 2.5mm² model as an example, with an outer diameter of approximately 4.2mm, the bending radius only needs 16.8mm). It can easily adapt to narrow or complex wiring spaces such as building suspended ceilings, wall concealed pipes, and behind furniture, reducing the risk of conductor breakage during construction and lowering the difficulty of disassembly during later line maintenance.​ From the perspective of application scenarios, the three specifications accurately match different electricity needs: the 2.5mm² model is mainly used for home lighting circuits, ordinary sockets (such as living room wall sockets, bedroom bedside sockets), and power supply for small household appliances (such as televisions and washing machines). Its long-term safe current-carrying capacity can reach 16-25A, meeting daily low-power electricity demand; the 4mm² model is suitable for high-power household appliance circuits (such as air conditioners, electric water heaters, and ovens) and ordinary power circuits in commercial buildings, with a safe current-carrying capacity of 25-32A, capable of coping with the instantaneous starting current of 2-3 horsepower air conditioners and 60L electric water heaters; the 6mm² model is mostly used for building main incoming lines, high-power electrical clusters in villas (such as whole-house water purification systems and floor heating boilers), and power cabinet connections in commercial places, with a safe current-carrying capacity of 32-40A, ensuring stable transmission of large currents and avoiding line overload and heating.​ In terms of insulation and safety performance, the cable uses a temperature-resistant PVC insulation layer (long-term temperature resistance of 70℃, short-term temperature resistance of 105℃), certified by the GB/T 5023.3-2008 standard. The insulation resistance is ≥100MΩ·km, and there is no breakdown under 1500V AC voltage for 1 minute, effectively isolating the conductor from external contact and preventing leakage risks. At the same time, the insulation layer has good aging resistance and wear resistance. During long-term use in building wall embedding or suspended ceilings, it can resist changes in environmental temperature and humidity (-15℃ to 70℃) and slight mechanical friction, extending the service life of the line. In addition, the product has also passed the GB/T 18380.1-2008 flame retardant test (ZC grade), which can self-extinguish quickly in case of fire, preventing flame spread and providing double protection for home and building electricity safety.​ In terms of construction and practicality, the surface of the BVR cable is printed with clear product identification (model, specification, rated voltage, production batch number, and implementation standard), using wear-resistant ink printing that remains legible after long-term friction, facilitating specification verification during construction and traceability during later maintenance. At the same time, its lightweight design (weight per kilometer is about 22kg for 2.5mm², 35kg for 4mm², and 50kg for 6mm²) reduces the intensity of construction handling. Combined with its flexible structure, it can reduce the resistance during dark pipe threading, improving construction efficiency, especially suitable for centralized wiring operations in high-rise buildings or large-area commercial spaces.
